论文摘要

使用基于偶极波数据包的驱动扩散方程的计算方法,我们模拟了嵌入了带有过渡金属二色元化(TMDC)异质性双层的光学微腔中偶极子的扩散动力学。通过考虑激子 - 偶极子,这是直接激子,间接激子和空腔光子的三种叠加,我们能够通过使用电压来驱动系统中的偶极子并研究其扩散性能。更确切地说,我们研究了在Mose2-WS2异质结构中存在的偶极子的传播,其中双齿式传播由ψ形通道指导。我们还考虑在ψ形通道中存在缓冲液的情况下二孔菌的传播,并研究效率变化。我们在室温下介绍了光路路由器的设计,并显示系统参数在内,包括〜2.0ev/mm的驱动力和60度的电场角度优化了我们的频道指南中的偶性重新分布效率。

Using a computational approach based on the driven diffusion equation for dipolariton wave packets, we simulate the diffusive dynamics of dipolaritons in an optical microcavity embedded with a transition-metal dichalcogenide (TMDC) heterogeneous bilayer encompassing a Ψ-shaped channel. By considering exciton-dipolaritons, which are a three way superposition of direct excitons, indirect excitons and cavity photons, we are able to drive the dipolaritons in our system by the use of an electric voltage and investigate their diffusive properties. More precisely, we study the propagation of dipolaritons present in a MoSe2-WS2 heterostructure, where the dipolariton propagation is guided by a Ψ-shaped channel. We also consider the propagation of dipolaritons in the presence of a buffer in the Ψ-shaped channel and study resulting changes in efficiency. We introduce designs for optical routers at room temperature as well as show that system parameters including driving forces of ~2.0eV/mm and electric field angles of sixty degrees optimize the dipolariton redistribution efficiencies in our channel guide.
